KABUL, Afghanistan – An Afghan official says a bomb blast has killed five children and a woman related to a Taliban commander. The children were playing with the bomb that the insurgent left inside his home.

Paktika governor's spokesman Mokhlis Afghan said Friday that the incident occurred in the Mata Khan district inside the house of a Taliban commander named Abdullah.

The commander had assembled a roadside bomb and left it inside his home, which he shared with relatives. It exploded when the children, from three to seven years old, began playing with it.

The spokesman said the bomb exploded Thursday morning.

The five children belonged to Abdullah's brother and wife, the spokesman said. The woman was the Taliban commander's sister. He had no other details.
